League wont launch only the logo appears

Hey guys, i'm having some trouble launching League. See as soon as i double-click the LeagueClient.exe file and run it as administrator, it show me the League of Legends logo, then it does nothing and eventually it will disappear. I tried resetting my router, reinstalling the game, updating and removing the drivers for my network card but nothing works. I even reinstalled all of League but nothing happened. This is why i took to the boards. I left my HRT logs in the link, and i hope any of you could help me. Every single bit of help is appreciated. My kindest regards, itsUmbra
